Using IR sensor and arduino to count RPM - #21 by Likayuu ...

2021-05-06· Ive build a belt gear drive to gear up an air motor. The air motor has a gear reduction of about 125:1 and I want to speed it back up. I built a table with 3, 1:5 gear ratios to get 1:125. On the last gear ratio I am using a belt instead of a chain. I want to measure the rotation speed of the last gear so if there is a failure my tachometer will be programmed to send a signal to a solenoid ...

IR line sensor? Reading rpm. - Interfacing - Arduino Forum

2009-07-21· I want to read rpm of an engine flywheel. I thought of either doing this with a hall effect sensor and magnet on the flywheel, or somthing else I have seen done is the flywheel painted black with a white line. There is a IR led directed at the flywheel and a IR sensor, when the white line passed the sensor it reflects the IR light to the sensor.

Arduino based RPM counter with a new and faster algorithm ...

This project is developed from scratch as an attempt to measure the exact RPM (Rotations per Minute)value of various motors using a single IR sensor, an Arduino board and an essential key ingredient -a Laser Pointer(necessarily Red).. This project uses the fact that the IR sensor also reads the the low number of IR radiations given off by the red laser.
